Best Whole House Air Purifier Reviews

In our search for the best whole house air purifier, we were totally surprised by the Airdog X8.

Its 5 stage filtration system doesn't just collect particles, it actually destroys viruses and bacteria —something we all can use in this day and age. With its washable and reusable collection plates you'll never need to buy another filter, which means less waste in the landfill and more cash in your wallet.

Probably the most impressive thing about the Airdog X8 is its clean air delivery rate (CADR).

This super high CADR means the Airdog X8 cleans upwards of 450 cubic feet per minute, making it one of the most effective air purifiers on the market.

With such a powerful system, you might expect the Airdog X8 to be the size of your washing machine, but you'd be wrong. Smaller than a kitchen chair, this unit will easily fit into any living space. And the Airdog X8 is so quiet you might not even notice it's running. If you're facing major air pollution, or other air quality issues, the Airdog X8 is a sure bet.
